2-Dimensional (2D) shapes

2D shapes have 2 dimensions, e.g. width and height.

An ellipse has 1 side, no corners, and 2 lines of symmetry.

triangle has 3 sides and 3 corners.

square has 4 equal sides, 4 equal corners, and 4 lines of symmetry.

A rectangle has 4 sides, 4 equal corners, and 2 lines of symmetry.

A rhombus has 4 equal sides, 4 corners, and 2 lines of symmetry.

A parallelogram has 4 sides in parallel pairs, 4 corners, and no lines of symmetry.

A kite has 4 sides, 4 corners, and 1 line of symmetry.

A pentagon has 5 sides and 5 corners.

A hexagon has 6 sides and 6 corners.

A circle has 1 side, no corners, and many lines of symmetry.

A sphere has 1 face and no edges or vertices.

A hemisphere has 2 faces, 1 edge, and no vertices.

A cone has 2 faces, 1 edge, and no vertices.
